Vessel Cap Having Straw

ABSTRACT

A vessel cap having a straw comprises a body mounted at a vessel inlet through which liquid material stored in a vessel is discharged outward, having a straw receiving portion at an upper surface thereof, and having a through hole at one side of the straw receiving portion; a straw horizontally disposed in the straw receiving portion of the body, and passing through the through hole thereby penetrating a sealing member formed at a vessel inlet when vertically positioned; and a connection film connected between an inner circumferential surface of the through hole of the body and an outer circumferential surface of the straw for guiding the straw to be vertically positioned. Once the straw is uprighted, the straw penetrates the sealing member. A user can drink the liquid material stored in the vessel by only one operation to open the cover thereby to enhance the user&#39;s convenience.

TECHNICAL FIELD

The present invention relates to a vessel cap having a straw, and more particularly, to a vessel cap having a straw capable of enhancing user's comfort by integrally forming a straw with a vessel cap.

BACKGROUND ART

FIG. 1 is a side view showing a vessel cap in accordance with the prior conventional art.

The conventional vessel cap is mounted at a vessel inlet 106 of a vessel 104 for storing liquid material 102 to drink, and serves to open and close the vessel inlet 106. A sealing member 108 for preventing the liquid material 102 stored in the vessel 104 from leaking is attached to the vessel inlet 106.

A locking rib 112 is protruding outward at a circumferential surface of the vessel inlet 106, and a locking jaw 114 locked by the locking rib 112 and coupled to the vessel inlet 106 is formed at a circumferential surface of the vessel cap 110. A handgrip 116 held by a user for detaching the vessel cap 110 from the vessel inlet is formed at one side of the vessel cap 110.

In the conventional vessel cap 110, when the user pulls the handgrip 116 upward, the locking jaw 112 formed at the vessel cap 110 is detached from the locking rib 114 formed at the vessel inlet 106 and thus the vessel cap 110 is detached from the vessel inlet 106.

Then, the sealing member 108 attached to the vessel inlet 106 is detached to drink the liquid material therein, or is penetrated with a straw.

However, in the conventional vessel cap 110, the sealing member 108 needs to be detached by the user's hand, thereby to cause user's inconvenience, and in addition, the sealing member 108 detached from the vessel inlet 106 has to be removed, thereby to cause environmental pollution.

Furthermore, in case of drinking the liquid material 102 by using a straw, the user has to carry an additional straw, thereby to cause user's inconvenience.

DISCLOSURE OF INVENTION Technical Problem

Therefore, an object of the present invention is to provide a vessel cap having a straw capable of enhancing user's comfort by integrally forming a straw with a vessel cap and capable of preventing the straw from being lost while being used.

The second object of the present invention is to provide a vessel cap having a straw capable of enhancing user's comfort by drinking liquid material stored in a vessel with only one operation to vertically position a straw without detaching a vessel cap from a vessel inlet so that the straw can penetrate a sealing member attached to the vessel inlet.

The third object of the present invention is to provide a vessel cap having a straw capable of effectively sucking liquid material stored in a vessel through a straw by vertically positioning the straw and by supplying external air into the vessel under a state that an air inlet formed at the vessel cap is opened.

The fourth object of the present invention is to provide a vessel cap having a straw capable of enhancing user's comfort by vertically positioning a straw, then downward pressing the straw, and penetrating a sealing member attached to a vessel inlet by the straw.

MODE FOR THE INVENTION

Hereinafter, preferred embodiments of the present invention will be explained in more detail with reference to the attached drawings.

FIG. 2 is a sectional view showing a vessel cap according to the first embodiment of the present invention, and FIG. 3 is a sectional view showing a state that a cover of the vessel cap is opened according to the first embodiment of the present invention.

A vessel cap according to the first embodiment of the present invention comprises a body 16 mounted at a vessel inlet 14 through which liquid material 12 stored in a vessel 10 is discharged outward and having a space therein, a straw 18 disposed in the body 16, and a connection film 20 connected between an inner circumferential surface of the body 16 and an outer circumferential surface of the straw 18 for horizontally arranging the straw 18 in the body 16 and guiding the straw 18 to be vertically positioned.

The vessel 10 for storing liquid material to drink can be formed of various materials such as a can, paper, or resin. A locking rib 22 for mounting the vessel cap 30 is protruding at the vessel inlet 14 in a circumferential direction. A sealing member 24 for protecting the liquid material 12 stored in the vessel 10 is attached to the vessel inlet 14.

A cover 26 for protecting the straw 18 disposed in the body 16 is mounted at an opened upper surface of the body 16. A locking jaw 32 locked by the locking rib 22 formed at the vessel inlet 14 for coupling the vessel cap 30 to the vessel inlet 14 is formed at a lower inner circumferential surface of the body 16.

One side of the cover 26 is rotatably connected to an upper end of the body 16 by a connection rib 34. A stopping hook 38 locked by a stopping protrusion 36 formed at the upper end of the body 16 is formed at the other side of the cover 26. A handgrip 40 held by a user so as to detach the cover 26 from the body 16 is formed at the cover 26.

As shown in FIG. 4, a locking portion 42 for maintaining a fixed state of the cover 26 to the body 16 is formed between the cover 26 and the body 16. The locking portion 42 comprises at least one locking protrusion 42 a downwardly extending at a lateral surface of the cover 26 and having an end of a spherical shape, and at least one locking groove 42 b formed at an upper end of the body 16 as a spherical shape for forcibly mounting the locking protrusion 42 a. Meanwhile, the cover 26 may be detachably coupled with the body 16.

The locking protrusion 42 a is provided with a notch portion 44 having a thin thickness and being divided when a force is applied to the cover 26 in an open direction.

That is, when a force is applied to the cover 26 in a closing direction, the locking protrusion 42 a formed at the cover 26 is forcibly fitted into the locking groove 42 b formed at the body 16. Accordingly, the locking portion 42 locks the cover 26 with the body 16. Under this state, if the cover 26 is opened, the notch portion 44 formed at the locking protrusion 42 a is divided and thus the locking the cover 26 with the body 16 is removed.

A supporting member 46 for maintaining a horizontal state of the straw 18 disposed in the body 16 when the cover 26 is closed and for vertically positioning the straw 18 when the cover 26 is opened is formed at an inner surface of the cover 26.

As shown in FIG. 5, the supporting member 46 is vertically formed at the inner surface of the cover 26 in one body. A mounting portion 48 for mounting an outer circumferential surface of the straw 18 is formed at a lower end of the supporting member 46. The mounting portion 48 has an opened lower surface and has elastic characteristics.

When the cover 26 is opened, the supporting member 46 is rotated with the cover 26 and thereby the straw 18 is uprighted. That is, since the mounting portion 48 holds the outer circumferential surface of the straw 18, when the supporting member 46 is rotated with the cover 26, the straw 18 is rotated together thus to be vertically positioned. When the cover 26 is more rotated, the mounting portion 48 is detached from the straw 18 and thus the straw 18 is uprighted.

The outer circumferential surface of the straw 18 is supported by the connection film 20 thereby to be horizontally positioned in the body 16. One end of the straw 18 is formed to be sharp so as to penetrate the sealing member 24 attached to the vessel inlet 14.

When the straw 18 is uprighted, the straw 18 has enough strength in order to penetrate the sealing member 24. In order to enhancing the strength of the straw 18, at least one reinforcing rib is formed at the straw 18 in a longitudinal direction.

As shown in FIG. 6, at least one reinforcing rib 50 is formed at the outer circumferential surface of the straw 18 in a longitudinal direction in order to reinforce the strength of the straw 18.

As another embodiment, as shown in FIG. 7, a reinforcing rib 52 having a straight line shape or a cross shape may be formed at an inner surface of the straw 18.

As still another embodiment, as shown in FIG. 8, a straw 54 of an oval sectional surface may increase strength by contacting a portion of longer diameter with the sealing member 24. As shown in FIG. 9, a straw 56 of a diamond sectional surface at the portion contacting the sealing member 24 may increase strength.

The connection film 20 is formed as a thin film having wrinkles to be flexibly transformed, and is integrally formed at the inner circumferential surface of the body 16. The connection film 20 seals the body 16 so that the liquid material can not leak to the upper side of the body 16.

The connection film 20 comprises a lower film 58 connected to a lower inner circumferential surface of the body 16, and an upper film 60 connected to an upper inner circumferential surface of the body 16. The straw 18 is disposed between the upper film 60 and the lower film 58.

When the straw 18 is uprighted, one end of the straw 18 exposed outward is positioned at an upper side of the lower film 58, and another end of the straw 18 that penetrates the sealing member 24 is positioned at a lower side of the upper film 60.

An operation of the vessel cap having a straw according to the first embodiment of the present invention will be explained.

When a user upwardly pulls the handgrip 40 of the cover 26 in order to drink the liquid material 12 stored in the vessel, locking of the locking portion 42 between the cover 26 and the body 16 is released and thus the cover 26 is detached from the body 16. That is, the notch portion 44 formed at the locking protrusion 42 a of the locking portion 42 is divided, thereby releasing the locked state between the cover 26 and the body 16.

Then, the supporting member 46 formed at the cover 26 is rotated upwardly together with the cover 26. As the result, the straw 18 locked by the supporting member 46 is rotated together with the supporting member 46 thus to be uprighted.

When the cover 26 is rotated by more than 90°, the mounting portion 48 of the supporting member 46 is detached from the straw 18 at the state that the straw 18 is uprighted.

Since one side of the straw 18 penetrates the sealing member 24 and another side of the straw 18 is exposed outside the body 16, the user inclines the vessel 10 and then drinks the liquid material 12 stored in the vessel 10 through the straw 18.

Since the straw 18 is supported by the connection film 20, the straw 18 is rotated, a portion of the straw 18 contacting the connection film 20 being a rotating point. Since the body 16 is sealed by the connection film 20, the liquid material 12 may be prevented from leaking outward even if the liquid material 12 is discharged through a hole of the sealing member 24 penetrated by the straw 18.

In the vessel cap according to the present invention, the straw 18 mounted at the body 16 penetrates the sealing member 24 and then is uprighted by only one operation to open the cover 26, thereby enhancing the user's convenience.

FIG. 10 is a sectional view showing a vessel cap having a straw according to the second embodiment of the present invention.

The vessel cap of the second embodiment has the same construction and operation as the vessel cap of the first embodiment except a coupling structure between the vessel cap and the vessel inlet.

In the vessel cap of the second embodiment, a female screw portion 62 is formed at a lower inner circumferential surface of the body 16, and a male screw portion 64 is formed at an outer circumferential surface of the vessel inlet 14. Accordingly, the female screw portion 62 is coupled to an outer circumferential surface of the male screw portion 64, thereby coupling the vessel cap 30 to the vessel 10.

A skirt 66 is formed at a lower end of the body 16 in a circumferential direction and is mounted at a neck portion of the vessel inlet 14, thereby coupling the vessel cap 30 with the vessel 10.

In the vessel cap of the second embodiment, in case of detaching the vessel cap 30 from the vessel inlet 14, the vessel cap 30 is rotated. As the result, the skirt 66 is divided, and the locking between the vessel cap 30 and the vessel 10 is released. If the vessel cap 30 is more rotated, the vessel cap 30 is detached from the vessel inlet 14.

FIG. 11 is a sectional view showing a vessel cap according to the third embodiment of the present invention, FIG. 12 is a plane view showing the vessel cap according to the third embodiment of the present invention, and FIG. 13 is a view showing an operation state of the vessel cap according to the third embodiment of the present invention.

A vessel cap having a straw according to the third embodiment comprises a body 70 mounted at a vessel inlet 14 through which liquid material 12 stored in a vessel 10 is discharged outward, having a space therein, and having an opened upper surface, a straw 18 disposed in the body 70 and horizontally supported by a supporting member formed at the body 70, and a connection film 72 connected between an inner circumferential surface of the body 70 and an outer circumferential surface of the straw 18 for arranging the straw 18 horizontally in the body 70 and guiding the straw 18 to be uprighted.

The body 70 is coupled to the vessel inlet 14 in the same manner as the aforementioned manner. The body 70 comprises an extension portion 74 extending in a side direction of the vessel inlet 14 for inserting one end of the straw 18, a press portion 78 formed at the end of the extension portion 74 and pressed by the user, and a bending portion 76 formed in the middle of the extension portion 74 and bent downwardly when the press portion 78 is pressed.

When the user presses the press portion 78, the bending portion 76 is bent downward and one end of the straw 18 is exposed outward.

The supporting member 80 is vertically formed at a lower surface of the body 70 and covers the outer circumferential surface of the straw 18 with an elastic force. Accordingly, the straw 18 can be horizontally disposed in the body 70.

A contraction film 82 for preventing external materials or dust from being introduced into the straw 18 covers one end of the straw 18. When the straw 18 is to be used, the contraction film 82 is removed.

The straw 18 is provided with a reinforcing rib to reinforce the strength thereof.

The connection film 72 is formed as a thin film wrinkles to be flexibly transformed, and is integrally formed at the inner circumferential surface of the body 70. The connection film 72 seals the body so that the liquid material may not leak to the upper side of the body 70.

An operation of the vessel cap having a straw according to the third embodiment of the present invention will be explained.

When the user presses the press portion 78 formed at the body 70, the extension portion 74 of the body 70 is bent on the basis of the bending portion 76. As the result, one end of the straw 18 is exposed outward. The straw 18 is upwardly rotated thereby to be uprighted.

The straw 18 is detached from the supporting member 80 and is rotated to be uprighted. The lower end of the straw 18 penetrates the sealing member 24, and the upper end of the straw 18 is exposed outward. The straw 18 is supported by the connection film 72 thereby to be rotated, and the body 70 is sealed by the connection film 72. Accordingly, the liquid material is prevented from leaking to the body 70.

FIG. 14 is a perspective view showing a vessel cap according to the fourth embodiment of the present invention, FIG. 15 is a perspective view showing a vessel cap in which a straw is horizontally positioned according to the fourth embodiment of the present invention, FIG. 16 is a perspective view showing a vessel cap in which a straw is vertically positioned according to the fourth embodiment of the present invention, and FIG. 17 is a sectional view showing the vessel cap according to the fourth embodiment of the present invention.

A vessel cap according to the fourth embodiment comprises a body 150 mounted at a vessel inlet 12 through which liquid material stored in a vessel 10 is discharged outward and having a straw receiving portion 152 at an upper portion thereof, a straw 154 horizontally disposed in the straw receiving portion 152 of the body 150, and a connection film 156 connected between an inner wall surface of the body 150 and an outer circumferential surface of the straw 154 for guiding the straw 154 to be vertically positioned.

The vessel 10 has the same construction as the vessel of the first embodiment, and a sealing member 24 for protecting the liquid material stored in the vessel 10 is attached to the vessel inlet 12.

The body 150 is formed as a cylindrical shape, and a cover member 158 for protecting the straw 154 disposed in the body 150 is detachably mounted at an opened upper surface of the body 150. A locking groove 160 for locking a locking rib 22 formed at the vessel inlet 12 and thereby coupling the vessel cap to the vessel inlet 12 is formed at a lower inner circumferential surface of the body 150.

The body 150 is provided with a through hole 162 at one side of the straw receiving portion 152. The straw 154 passes through the through hole 162 and penetrates the sealing member 24.

A female screw portion is formed at an inner circumferential surface of the body 150, and a male screw portion is formed at an outer circumferential surface of the vessel inlet 12. Accordingly, the body 150 can be coupled to the vessel inlet 12 by a screw couple method. Besides the aforementioned coupling method, the body 150 can be detachably coupled to the vessel inlet 12.

The straw receiving portion 152 of the body 150 for positioning one end of the straw 154 is provided with an opening 164 so that the user can easily position the straw 154 vertically by holding it.

The cover member 158 is attached to an upper circumferential surface of the straw receiving portion 152 of the body 150 by an adhesion method, a thermal fusion method, etc. One side of the cover member 158 covers up to the opening 164 of the straw receiving portion 152.

A supporting member 166 for supporting the straw 154 horizontally positioned in the straw receiving portion 152 is vertically formed at a bottom surface of the straw receiving portion 152 of the body 150. As shown in FIG. 18, the supporting member 166 is constructed as one pair vertically positioned at the bottom surface of the straw receiving portion 152. Also, a mounting groove 168 for elastically mounting the straw 18 is formed at inner surfaces of the supporting members facing each other. An air inlet 170 for supplying external air into the vessel 10 is formed at the center of the supporting member 166.

When the straw 154 is inserted into the mounting groove 168 of the supporting member 166, the outer circumferential surface of the straw 154 is fitted into the mounting groove 168 and thus the air inlet 170 is closed. On the contrary, when the straw 154 is detached from the supporting member 166 thus to be uprighted, the air inlet 170 is opened and thereby external air is supplied into the vessel 10 through the air inlet 170.

When the user sucks the liquid material stored in the vessel 10, the liquid material can be more effectively sucked through the straw 154 since external air is supplied into the vessel 10 through the air inlet 170.

The air inlet 170 can be penetratingly formed at the body 150 besides the center of the supporting member 166. Also, the air inlet 170 can be formed at any part only if external air can be supplied into the vessel 10.

Under a state that the outer circumferential surface of the straw 154 is supported by the connection film 156, the straw 154 is horizontally arranged in the straw receiving portion 152 of the body 150. One end of the straw 154 is positioned at an upper side of the connection film 156, and another end of the straw 154 is positioned at a lower side of the connection film 156. Another end of the straw 154 positioned at the lower side of the connection film 156 is sharply formed so as to easily penetrate the sealing member 24 attached to the vessel inlet 12.

A cut portion 172 for effectively introducing the liquid material stored in the vessel 10 is formed in a longitudinal direction at another end of the straw 154 that penetrates the sealing member 24 and is positioned in the vessel 10. That is, as shown in FIG. 19, when the user sucks the liquid material stored in the vessel 10 by inclining the vessel 10, the liquid material can be easily sucked completely through cut portion 172 of the straw 154.

As shown in FIG. 20, one end of the straw 154 being positioned at the upper side of the connection film 156 and contacting the user's lip has a diameter less than a diameter of another end of the straw 154 positioned at the lower side of the connection film 156 and penetrating the sealing member 24. Accordingly, strength of the straw 154 positioned at the lower side of the connection film 156 and penetrating the sealing member 24 is increased. A punch portion 180 having a sharp shape to penetrate the sealing member 24 is formed at the end of the straw 154.

The upper end of the straw 154 contacting the user's lip is provided with a contraction film 182 for preventing external materials of dust from being introduced into the straw 154. At the time of using the straw 154, the contraction film 182 is removed.

A straw closing portion 184 for closing another end of the straw 154 when the straw 154 is horizontally positioned in the straw receiving portion 152 after the user stops drinking the liquid material stored in the vessel 10 is formed in the body 150.

The straw closing portion 184 is protruded in the body 150, and a packing groove 186 is formed at an inner surface of the straw closing portion 184 with the same shape as that of another end of the straw 154. Accordingly, when the straw 154 is horizontally positioned, another end of the straw 154 is closely contacted to the packing groove 186 and thus the straw 154 is sealed.

When the straw 154 is uprighted, the straw 154 needs enough strength in order to penetrate the sealing member 24. In order to reinforce the strength of the straw 154, a reinforcing rib is formed in a longitudinal direction of the straw 154.

As shown in FIGS. 20 and 21, the straw 154 is provided with a reinforcing rib 188 having a straight line shape or a reinforcing rib 176 having a cross shape at an inner circumferential surface thereof.

As another embodiment, as shown in FIG. 22, a straw 190 is formed to have an oval sectional surface. An strength of the straw 190 is increased by contacting a longer diameter to the sealing member 24. As shown in FIG. 23, a straw 192 of a diamond sectional surface at the portion contacting the sealing member 24 may increase strength.

The connection film 156 is formed as a thin film wrinkles to be flexibly transformed, and is integrally formed between the inner circumferential surface of the through hole 162 of the body 150 and the outer circumferential surface of the straw 154. The connection film 156 seals the body so that the liquid material can not be leaked to the upper side of the body 150.

The connection film 156 guides the straw 154 to be moved under a connected state to the body 150 when the straw 154 is uprighted or is horizontally positioned.

An operation of the vessel cap having a straw according to the present invention will be explained.

FIGS. 24 and 25 are views showing an operation state of the vessel cap according to the fourth embodiment of the present invention.

When the user is to drink the liquid material stored in the vessel 10, the user pulls the cover member 158 formed at the upper portion of the body 150.

Then, the user positions the straw 154 vertically with holding one end of the straw 154. As the result, the straw 154 is detached from the supporting member 166 and is guided by the connection film 156, thereby being upright. The sharp end of the straw 154 penetrates the sealing member 24 thus to be positioned in the vessel 10, and another end of the straw 154 is exposed outside the body 150.

Under the state, the contraction film 182 that covers one end of the straw 154 is removed and the vessel 10 is inclined, so that the user sucks the liquid material stored in the inclined vessel 10 through the straw 154.

If the straw 154 is vertically positioned, the air inlet 170 formed at the supporting member 166 is opened and thus external air is introduced into the vessel 10 through the air inlet 170. Accordingly, the liquid material stored in the vessel 10 can be more sucked.

When the user stops drinking the liquid material stored in the vessel 10, the straw 154 is horizontally positioned and one end of the straw 154 is fitted into the mounting groove 168 of the supporting member 166. As the result, the outer circumferential surface of the straw 154 is adhered onto the air inlet 170 thereby to block the air inlet 170, and another end of the straw 154 is closely contacted to the packing groove 186 of the straw closing portion 184 formed in the body 150 thereby to seal the straw 154.

Accordingly, when the user stops drinking the liquid material, the liquid material stored in the vessel is prevented from leaking outward through the vessel cap since the straw 154 is closed and the air inlet 170 is blocked.

Furthermore, when a little amount of the liquid material remains in the vessel 10, the liquid material is sucked through the cut portion 172 formed at the end of the straw 154. Accordingly, even a little amount of the liquid material can be sucked completely thereby to enhance the user's comfort.

In the vessel cap according to the present invention, the user has only to position the straw 154 formed at the body 150 vertically so that the straw 154 can penetrate the sealing member 24, thereby enhancing the user's convenience.

A mounting portion 342 for mounting the outer circumferential surface of the straw 310 is formed at facing surfaces of the first rod 338 and the second rod 340. The first rod 338 and the second rod 340 elastically support the straw 310 mounted at the mounting portion 342.

When the cover 308 is opened, the supporting rod 336 is rotated together with the cover 308 thereby to position the straw 310 vertically. That is, since the outer circumferential surface of the straw 310 is mounted at the mounting portion 342, when the supporting rod 336 is rotated together with the cover 308, the straw 310 is rotated together thereby to be uprighted. When the cover 308 is more rotated, the straw 310 is detached from the mounting portion 342 thereby to be uprighted.

Under a state that the outer circumferential surface of the straw 310 is supported by the connection film 312, the straw 310 is horizontally disposed in the body 306. A punch portion 346 having a sharp shape so as to easily penetrate the sealing member 320 attached to the outlet 302 is formed at the end of the straw 310.

The connection film 312 is formed as a thin film wrinkles to be flexibly transformed, and is expanded upwardly or contracted downwardly. The connection film 312 is integrally formed between the inner circumferential surface of the body 306 and the outer circumferential surface of the straw 310. The connection film 312 seals the body so that the liquid material can not be leaked to the upper side of the body 306.

An operation of the vessel cap having a straw according to the eighth embodiment of the present invention will be explained.

FIGS. 40 and 41 are views showing an operation state of the vessel cap according to the eighth embodiment of the present invention.

When the user upwardly pulls the handgrip 332 of the cover 308 in order to drink the liquid material stored in the vessel, the locking protrusion 330 formed at the cover 308 is detached from the locking groove 328 formed at the body 306. As the result, the cover 308 is rotated centering around the hinge rib 326 thereby to be opened from the body 306.

Under the state, the supporting rod 336 formed at the cover 308 is upwardly rotated together with the cover 308. The straw 310 elastically mounted at the mounting portion 342 of the supporting rod 336 is rotated together with the supporting rod 336 thereby to be uprighted.

When the cover 308 is rotated by more than 90°, the straw 310 is uprighted and the mounting portion 342 of the supporting member 336 is widened thereby to detach the supporting rod 336 from the straw 310.

When the straw 310 is downwardly pressed, the punch portion 346 formed at the end of the straw 310 penetrates the sealing member 320 formed at the outlet 302 of the vessel 300, and another end of the straw 310 is exposed outside the body 306. Accordingly, the user inclines the vessel 300 and then sucks the liquid material stored in the vessel 300 through the straw 310.

The connection film 312 disposed between the straw 310 and the body 306 has a wrinkle type. When the straw 310 is uprighted, the connection film 312 is expanded. On the contrary, when the straw 310 is pressed downwardly, the connection film 312 is contracted thereby to guide the straw 310 to downwardly move.

In the vessel cap according to the eighth embodiment, when the user opens the cover 308, the straw 310 mounted at the body 306 becomes right. On the contrary, when the user downwardly presses the straw 310, the straw 310 penetrates the sealing member 320. Since the straw 310 is stored in the vessel cap, the user's convenience is enhanced.
